RADIATOR.

Specification' of Lettere Patent.

Patented Jan. 28, 1908.

Appiiaaon nea January 27. 1904. sein Na 190.791.

To llw-hom may concern: Be 1t known. that I, Jol-TAN AUGUsT LrD- AVAL-L, a subject of the King of Sweden, and

resident of Geile, Sweden, have invented new and useful Improvements in Radiators, of which the following is a specification, reference being had to the drawing accompanying and forming a part hereof. y

This invent-ion relates to improvements in radiators for heating purposes having-retti cal flanges or'ribs on their outer sides.

The object of the invention is-to provide radiators of such construction that the horizontal section of the same, while using only some few patterns, may be changed at-will so as to suit different localities.

The invention consists in that the sidewalls of the radiators, the horizontal crosssection of which is in well known manner wave-sha ed, zigzag-shaped or the like, are compose( of a number of separate ieces which may bev flat orcurved, the sai( sidewalls being connected to cover' and bottoniieces the shape of-'which corresponds tothe horizontal section of the radiator.

In the accompanying drawing I have shown some radiators embodying my invention.

Figure 1 shows a side-elevation of a radiator, Fig. 2 a vertical section and Fig', 3 a hori- Figs. 4, 5 and 6 show horlzontal sectlons of parts of radiators Referring to Figs. 1, 2, and 3, the side-walls iiat pieces 1,-which in well-known manner are provided with langesror ribs 2 on the one` side. At the adjacent edges the said'pieces 1 may be provided with flanges 3 or the like for connecting together the same by means of screws, rivets, or the like (not shown). The cover and bottom pieces 4 and 5 (Fig. 2)

.may, suitably, be of curved cross-section and are in any convenientmannersecured to the side-walls 1. Some of the said pieces 4 and 5 maybe provided with soot-holes and doors 6, the latter being at the bottom of the radiator and held in position-by n ieans of yokes 8 secured to the ribs 2 in an convenient manner.

Referring to Fig. 4, t ve pieces 7 constituting 'the sides of the radiator are curved 1n such manner that the radiator obtains Wave- 4 shaped horizontal cross-section. In ord'er to facilitate the forming and casting of the said pieces 7,- all theflanges except those serving to connect .the several Ipieces together are made parallel to each other.

Figs. 5 and 6 show each a constructional i form of radiators, thev side-walls of which vare com osedof flat pieces as in Figs. 1-3.

Q viously I do not limit 'myself exactly to the vconstructional forms shown in the drawing, in' as much as the radiators when conrposed of flat'or curved side pieces of coinparatively small extension in horizontal direction may obtain any desired shape in horizontal section without varying the'shape of the said side-pieces as will be easil f understood by'those skilled in the art to w lich this invention appertains.- p

The radiators constructed 11i-accordance lwithinycpresent invention may suitably be connecte to the connecting ipes, or the like, in such manner that the leating agent will flow into the saine at the upper part of the one end 'and flowout at the lower part of the other end.. On account of thezigzagshaped, wavefshaped, or similar horizontal section the improved radiators are comparatively elasticv in longitudinal direction and may therefore be made of large extension in the said direction without anv danger of the Aconnections between the radiators and the conductors being broken.

Having now particularly described my invention and in Nwhat manner the same may be performed, what I claim as new and dem sire' to secure by Letters Patent is:

In a radiator, the combination of sidewalls formed *of sections of a great height in comparisonwith the length thereof, said'sections being connected together in such a manner as to form a 'assage o f a tortuous horizontal section, an c overand bottompiece's of a shape corresponding to the horizontal section of the radiator, said pieces being Secured to the side-walls, substantially as and lfor the purpose set forth.

I'n testimony whereof I have signed my narne to this specification in thepresence of two subscribing witnesses.- s
